Why Are Your Patio Doors Drafty?
A leaky patio door costs more than comfort, it drives up summer energy bills, brings in humid air, and makes your home less secure. If your living room or kitchen feels like a ducted vent during summer, the door is often the weak link.
This guide walks through why drafty patio doors happen in South Louisiana, how to pick the right replacement for humid, hurricane-prone conditions, and what to expect during installation.
In South Louisiana the combination of high humidity, frequent storms, and salty air accelerates wear on seals and hardware, so components that last a decade inland may fail sooner here.
A quick diagnostic is to run your hand along the jambs, lift the handle and see if the latch seats fully, and inspect the bottom sweep and threshold for cracks or missing material. An experienced company can confirm the cause with a quick inspection.
Repairing Vs. Replacing
But when the frame is rotted, warped, or the door repeatedly leaks after fixes, replacement is the smarter long-term choice. Replace the door when you see wood decay at the sill, rusted rollers or tracks, glass fogging between panes, or you want improved energy performance.
What to Look for in a Replacement Door
Selecting a replacement for South Louisiana means prioritizing materials and features that resist humidity, reduce heat gain, and meet local windborne-debris requirements when applicable.
Wood doors look traditional, but in South Louisiana they require diligent maintenance or protective cladding to avoid rapid decay.
A low solar heat gain coefficient reduces cooling load on hot afternoons, while double-pane insulated glass keeps interior surfaces cooler and cuts energy use.
Proper flashing, a backer rod and sealant at the sill, and through-fastening into structural framing prevent water intrusion more reliably than surface caulks alone.
Installing Your New Patio Door
Installers check the opening with a torpedo level, shim to maintain drainage slope, and install a sill pan to carry water out instead of letting it collect under the threshold.
Expect a full replacement to take a few hours for a single unit with a competent crew, or a day or two if modifications to the opening, siding, or deck are required.
Get multiple Scott Window Replacement written estimates that separate product cost from labor and materials so you can compare apples to apples.
Good contractors will show examples of similar jobs, explain how they handle water management, and provide a clear line-item estimate rather than a single lump-sum figure.
Keep the product paperwork and warranty information in case follow-up adjustments or repairs are needed.
Replacing a drafty patio door is an investment that reduces cooling costs, improves comfort, and lowers the chance of moisture damage to interior finishes.
